Mike Conley 52676fa9cc Bug 1069075 - Send location along with CTP messages. r=gfritzsche.
Before, we were comparing Principals sent up from PluginContent against the
Principal of the selected browser - this was in order to account for races
(and intermittent oranges) where the browser has moved away from a page before
a CTP message has been received by the parent.

Comparing Principals works beautifully, except in the case of Data URIs, since
Data URIs inherit the Principals of the page they were linked from. That means
that if we're on a page with a link to a Data URI that embeds a plugin, if we
quickly browse to that page and back before a CTP message reaches the parent,
when the CTP message finally arrives, the Principals will match. We solve this
by sending the location as well as the Principal, to do a final comparison if
the Principals do match.
